Fix forced loop termination in nscd database lookup.
There are two issues with the forced loop exit in the nscd lookup:
1. the estimate of the entry size isn't pessimistic enough for all
databases, resulting potentially is too early exits
2. the combination of 64-bit process and 32-bit nscd would lead to
rejecting valid records in the database.

again from memory once we verified it, and make sure the trailing

Don't try to cleanup libselinux and libaudit.

Fix change to prevent cancel signal in unsafe places.
The bits tested to decide when to delay the return when switching

No cancel signal in unsafe places.
When disabling async cancellation we cannot return from the function
call if the thread is canceled. This happens when the cancel bits
have been set before async cancel is disabled but the signal hasn't
been sent/received yet. Delay for as long as necessary since
otherwise the signal might be received in an unsafe context.
